Hmm... ah do bleev (IIRC) that I was experiencing the problem when the wakeup-call was at 0329, so I backed off 9 more minutes, hence 0320. However, I'll reset the wakeup to 0329 and see what happens, to report back in a day or three.
As ever, tnx for the feedback, dnanian; and also to you, DaleMeyn.
Glad the known issue is display only; as I said, the SAT 0330 backup (which was one of those that "took")
did happen despite that buglet, so I guess that agrees w/the data.
